    While this is related to an add-on, I'm still asking because this error never appeared when running 1.4:

    Is it a problem with the add-on or with XF 1.5?

    Relatively confident that it's an add-on. But the simple test would be, if you can reproduce it reliably, to disable the add-on and try again.

    This happened a few days ago and have not happen again (and the add-on has been used many times since then). Maybe it was what developers call a "race condition"?

    Could you please provide a bit more details about that specific error? Is it a serious one or could it be missed?

    Best report the issue to @Liam W and he can try fix or advise if it is an XF issue.

    Before bothering him I'm trying to see if it is a serious issue or not because it has happened only one time since I upgraded to 1.5. When I was on 1.4 I never saw that error.

    We didn't actually touch any Conversation code in 1.5 so the version change should be unrelated.

    It's a weird error. It's actually one that shouldn't be possible, at all in the existing code.

    It seems to me as though it's happening as the result of a reply being inserted into an existing conversation, but that code should only be happening when a new conversation is being created.

    Definitely an issue that seems like it might be add-on related.
